Question

which statements describe an object in motion that has no external force acting on it? check all that apply. it accelerates and speeds up. it moves at a constant speed. it decelerates and slows down. it changes direction. it moves in the same direction.

Explanation:

According to Newton's first - law of motion, an object in motion with no external force acting on it will move at a constant velocity. Constant velocity means moving at a constant speed and in the same direction. Acceleration (speeding up, slowing down, or changing direction) requires an external force.

Answer:

It moves at a constant speed.
It moves in the same direction.
